A first locking groove 11 and a second locking groove 12 are respectively formed on one side of the plastic housing 1. The grounding terminal 2 is fitted into the first locking groove 11, and a fourth groove 20 is formed on the grounding terminal 2, which is engaged with a first latch 13, which is fixed in the first locking groove 11. The right channel terminal 4 is fitted into the second locking groove 12, and a fifth groove 21 is formed on the right channel terminal 4, which is engaged with a second latch 14, which is fixed in the second locking groove 12. A grounding terminal is welded to the bottom of the plastic housing 1. 2 and right channel terminal 4; the top of the plastic housing 1 has a first groove 9 and a second groove 10, the first groove 9 is fitted with the positive terminal 5 of the microphone and the other end of the first detection terminal 6, the second groove 10 is fitted with the negative terminal 7 of the microphone and the other end of the second detection terminal 8; a third groove 19 is opened on the adjacent side of the plastic housing 1, the third groove 19 is fitted with the other end of the left channel terminal 3; a baffle 15 is attached to the side of the plastic housing 1 with the third groove 19, and the baffle 15 is connected to the left channel terminal 3. The baffle 15 is set to prevent metal objects with a diameter of 1mm from entering the product from the outside, causing risks such as PCB short circuit; a positioning post 16 is set on the plastic housing 1 to make the welding material easier to melt and the product welding more secure; a microphone 17 is attached to the bottom of the plastic housing 1 to facilitate the automatic picking up of the product by the customer process; the plastic housing 1 is fixedly connected to the port 18, which is convenient for the insertion of the headphone plug.

[0020] Specifically, in use, the plastic housing 1 is manufactured by injection molding. After the plastic housing 1 is manufactured, the first groove 9, the second groove 10, the third groove 19, the fourth groove 20, the fifth groove 21, the first snap-fit ​​groove 11, and the second snap-fit ​​groove 12 are formed respectively. Then, one end of the microphone positive terminal 5, the first detection terminal 6, the microphone negative terminal 7, the second detection terminal 8, the left channel terminal 3, the ground terminal 2, and the right channel terminal 4 are fitted into the plastic housing 1, while the other end of the microphone positive terminal 5 and the first detection terminal 6 are fitted into the plastic housing 1.

The right microphone negative terminal 7 and the second detection terminal 8 are also disconnected, forming an open circuit. The microphone positive terminal 5 acts as a contact plate, and the first detection terminal 6 acts as a spring contact, forming a detection switch. At the same time, the microphone negative terminal 7 acts as a spring contact, and the second detection terminal 8 acts as a contact plate, forming another detection switch. When the plug is inserted, the two contact plates and spring contacts are disconnected, forming an open circuit. When the plug is pulled out, the contact plates and spring contacts are in contact, forming a short circuit. This creates an effective electrical circuit between the plug and the socket connector. The left channel terminal 3, the right channel terminal 4, and the ground terminal 2 ensure the effective transmission of stereo audio signals, thereby providing better audio transmission quality. The microphone positive terminal 5 and the microphone negative terminal 7 provide functions such as call or playback control, offering more functional options.
